Evaluation of uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), and aberrations were performed 6-months postoperatively. The anterior segment parameters were collected using CASIA2 anterior segment-optical coherence tomography, tilt and decentration of ICL V4c were analyzed using MATLAB software.

No significant changes were observed regarding higher-order and spherical aberrations after the operation; however, coma and trefoil significantly increased compared to preoperative values. The average total decentration and tilt was 0.21\u2009\u00b1\u20090.12\u00a0mm and 2.54\u2009\u00b1\u20091.00\u00b0, respectively.

The most common visual symptom was halo, and 97.04% of patients had a satisfaction score\u2009\u2265\u20098.
